You will want to put your LOC up front because in the rear your speaker wires aren't close enough to get them to the LOC without running excess wire.



In order to splice into this line, you will want to cut one wire at a time from your speaker output (you can find a wiring diagram online or at the library in a Chilton's manual), strip the insulation off both new ends, put some heat shrink wrapping on one side, twist the three wires (both positives ((or negatives)) from the speaker line and the positive ((or negative)) from the corresponding ((left or right)) input on your LOC) then you will apply heat by soldering iron or industrial hair drier to srink the heat shrink over your solder.



As far as your remote wire, you will have to find a wire that connects to your ignition with a relay. If you have a cigarette light that doesn't work when your ignition is off, you can use the 12v line in that. If you don't have one of those it's back to the wiring diagrams and find the wire that connects to your ignition.



Best wishes.
